“My husband [Austin Hearst] has been on the board of Save the Children forever, and I’ve seen them in action. They’re the first ones there in tough situations and are extremely productive in their goal to protect children,” Hearst told me. Rallying for the cause, Hearst enlisted some classic beauties like Dakota Fanning, Lauren Hutton, and Miroslava Duma—the latter two in attendance at lunch—to pose for the collaboration’s campaign, which was shot by photographer Hans Neumann.

Hearst’s airy townhouse was an ode to cozy, thoughtfully chic style. Guests milled about on the second floor, where an open kitchen connects the sitting room and dining room. Little details like wooden Matthew Hilton dining chairs and the antique brass lighting flanking the kitchen’s island made way for the space’s pièce de résistance: a large neo-Surrealist work by Argentine painter Diego Gravinese. Attendees including Rebecca Hall, Anh Duong, and Kate Young ate small plates of light Italian fare; favorites included spinach gnocchi, lobster salad, and tiny foie gras pastries. Overall, a rare low-key but powerful afternoon.
